For a challenge that was conceptually very similar to Day 19, this one completely broke me all over again. I think it was just near impossible to mentally visualize. I only got it with lots of reading your code, so thanks!

I like your short cut of converting the keys from a grid to a set of coordinates, which really simplifies how you get the path.

Glad to be able to help. This one really was a doozy.
